A plan to provide free healthcare to all along the lines of what has been proposed by Vermont Sen. Bernie Sanders and endorsed by Democratic front-runner Massachusetts Sen. Elizabeth Warren will now cost $34 trillion over a decade, according to a new estimate from the liberal Urban Institute.

The think tank authored a much-cited study that pegged the cost of the Sanders 2016 campaign proposal at $32 trillion, but four years later they have determined that his updated plan, which includes enhanced benefits, would cost the federal government even more.
